Abstract
Using as primary excitants ultraviolet light and polonium alpha-particles, the phosphorescent afterglow of the double banded phosphor, silver-activated sodium chloride, has been measured as a function of the time with photosensitive Geiger counters and photomultiplier tubes. The decay curves of the phosphorescent intensity of the two bands can be represented by appreciably different power laws. Decay slopes greater in absolute magnitude than two on a plot have been frequently observed.
